The purpose of this course is to enable students to master the basic operations of commonly used instruments and equipment in this course through the study of functional experiments, and to be familiar with the main methods of functional experiments and the general techniques of laboratory animals. Understand the relevant contents of experiments in vivo animal experiments, electrophysiological experiments, in vitro organ experiments, pathological model experiments, preclinical pharmacology, toxicology experiments, and the principles and methods of related experiments. Through the above experiments, students can systematically understand and master the content and methods of the experiment, so that they have a certain degree of practical ability.
